SNOW-PLOW.

Specification of Letters Patent.

Patented Nov. 7, 1905.

application filed April 28, 1905- Serial No. 257,908.

1'0 all whom if may concern:

Be it known that I, IIOWARD GRInEs,a1-esi dent of .\ewc0mb, in the county of Essex and State of .\ew York, have invented certain new and useful Improvements in Snow-Flows; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to impr vements in snow-plows, and more particularly to improvements upon the construction disclosed in Patent No. 751,183, granted February 2, 190-1, to Stephen D. Lamos, the object of the invention being to provide improved mounting for the plows which permits their ready adjustment up and down; and the invention consists in certain novel features of construc tion and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in side elevation illustrating my improvements, and Fig. '2 is a top plan view.

1 1 represent long parallel runners having depending guide-plates 2 and connected at their forward ends by a rod 3, to which the sled tongue I is secured, and a scraper or plow 5 is secured to a frame 6 between the forward end of runners 1 1 by a bolt and set nut to lock the scraper or plow in any position of vertical adjustment, and thereby secure it in operation or not, as desired.

Auxiliary runners 7 7 are pivoted at their rear ends to main runners 1' 1 by bolts 8, and depending tongues 9 are secured to a frame or box 10 on the main runners, and these tongues project down beside'auxiliary runners 7 7 and serve as guides therefor, preventing any lateral deflection thereof.

Pious 11 are secured to the forward ends of these auxiliary runners 7 7 and with the aid of pivoted wings 12 at the rear ends of the plows serve to carry. the snow to the sides. I hese wings 12 are pivotally supported on a cross-bar 13 and are held at any angle by means of adjustable cross-bars 15, as more clearly (pointed out in the Lamos patent above referre to.

Supported to turn in internally screwthreaded sleeves 16 at the sides of frame 10 are vertical screws 17, which latter are connected at their lower ends to the auxiliary runners 7, and crank-handles 18 are secured on the upper ends of these'screws 17 to facilitate their adjustment. Byj turning these 1 screws 17 in one direction the auxiliary runl ners 77 and plows 11, carried thereby, will be elevated out of contact wit-h the ground, and the sled can run on its main runners 1 1 and be moved from place to place without the operation of the plows. 'hen the plows are desired, the screws 17 are turned in the opposite direction, forcing down the forward ends of the auxiliary runners and moving the plows to operative position, and by means of these screws the plows can be adjusted up and down to any position desired with but slight exertion on the part of the operator.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a sled, of auxiliary runners connected therewith, means for adjusting said auxiliary runners up and with said auxiliary runners.

2. The combination with a sled, of auxiliary runners pivoted at their rear ends to the sled, plows secured to the forward ends of the auxiliary runners. and means for adjusting said auxiliary runners up and down.

3. The combination with a sled, of auxiliary rulmerspivoted at their rear ends to the sled, plows carried by the forward ends of the auxiliary runners, a frame on the sled, means on said frame for guiding the auxiliary runners, and means on the frame for moving the auxiliary runners vertically.

4. The combination with a sled, of auxiliary runners pivoted at their rear ends to the sled, plows carried by the forward ends of the auxiliary runners, a frame on the sled, overhanging tongues secured to the frame and guiding vertical movement of the auxiliary iliary runners and movable with the latter, a
